6 Claims.

This invention relates to improvements in cable-anchoring devices.

This application is a division of my application filed April 28, 1937,Serial No. 139,485 now Patent No. 2,203,066, granted June 4, 1940, forCable anchoring devices, the device illustrated in the drawings anddescribed hereafter being substantially identical to that illustrated inFigs. to 10, inclusive, of said application filed April 28, 1937.

As in my application filed April 28, 1937, it is an object of thisinvention to provide a cableanchoring device having a freely movableclamping member adapted to act as a snubbing element and to be actuatedby the cable into clamping engagement therewith.

A further object is to provide in a cable-anchoring device, a snubbingand clamping member which is movable relative to its coacting supportingelement to a position permitting the cable to be looped about the memberwithout interference by the supporting element and which may then bereplaced in operative snubbing and clamping relation to the supportingelement which serves as means for preventing disengagement of the cablelaterally of the device.

It is also an object to provide a cable clamp which will permit thecable to be first formed into a loop at its anchoring end and thenpassed through an aperture in the device, the loop then receiving asnubbing and clamping member which will prevent removal of the loop fromthe aperture and automatically clamp the cable to the device under theinfluence of Weight or tension of the cable.

Further objects are to provide in a cable-anchoring device with parallelsides, a circular snubbing element pivotally cooperative with said sidesand wholly removable therefrom and which may be replaced to operativeand clamping position with relation to said sides for clamping a cablethereto.

The following description will disclose a cableanchoring device fromwhich a cable may be easily removed without mutilating the cable or thedevice and from which the cable may be easily released after shiftingthe stresses produced by the cable from the device.

In the drawings:

Fig. 1 is a side view in elevation of this invention.

Fig. 2 is a top plan view of the device.

Fig. 3 is a right-end view of the device shown in Fig. 1.

Fig. 4 is a view similar to Fig. 3 illustrating a modified form ofsnubbing and clamping ment.

Fig. 5 is a view illustrating a modified form of snubbing and clampingelement.

ele-.

Fig. 6 is a bottom plan view of the device shown in Fig. 5.

Like parts are identified by the same reference characters throughoutthe several views.

The device shown in Figs. 1, 2 and 3 comprises an elongated, generallyrectangularlyshaped slide member IA providing an elongated opening 2 forreceiving the looped end of a cable I and within which the snubbing andtubular clamping member 3 is movable. The member IA is preferably formedof round stock and may be reinforced by a cross-bar if desired at thebail end 5. After the rod has been bent to the shape indicated, the endsare brought together at 6 and welded. The end I of the member IA servesas a clamping portion cooperating with the element .3 to preventslipping of a cable about the element when anchored thereto. When theelement 3 is disposed between the sides 9 and II, the axis about whichthe element 3 is generated extends transversely to the sides 9 and II.

As clearly shown in Fig. v1, the element 3 is preferably made of tubingand is provided at one end with a pair of concentric apertures 8, theaxes of which are transversely extended relative .to the axis of thetube and are laterally to one side of the tube axis. These aperturesreceive one side 9 of [the member IA. The opposite end In of the member3 is cut at a bevel and serves as a contact margin engaging the side IIof the member IA and preventing the pivotal movement of the element 3 inone direction but permitting it in the other direction.

From the foregoing, it will be seen that in the device shown in Figs. 1through 3, the element 3 (shown in Fig. 4 as element 3A) is capable ofbeing moved in two general directions relative to the slide member andtransversely in a plane normal to longitudinal direction of movement orto the slide member.

A .cable I is anchored to the device disclosed in Figs. 1, 2 and 3 asfollows, reference being made specifically to Fig. l: The cable I isformed into a loop which is passed through the opening 2 afterwithdrawing the element 3 from the opening by pivotal movementdownwardly about the side '9 of the member IA. When the loop is passedthrough the opening, the element 3 is moved into the loop so that thecable passes beneath the element and upwardly between the element 3 andthe clamping portion I on, the memberIA.

As clearly indicated in Fig. 1, the main portion or" the element 3 isdisposed below the member IA so that it will 'be drawn upwardly with itsangular margin I0 engaging the side I! of the member IA. Obviously, ifthe cable .;is under tension, it will cause theelement 3 to "slidetoward the clamping portion 7 and securely hold the cable againstwithdrawal.

The snubbing and clamping element 3A shown in Fig. 4 is a modificationof that shown in Figs. 1 and 2 in that the beveled margin 10A terminatesin a shoulder l2 which engages the side I l of the member I andminimizes any tendency .to.

spread the sides of the member. Otherwise the device illustrated in Fig.4 operates the same as that described with reference to Figs. 1, 2 and3.

Figs. 5 and 6 illustrate a cable-anchoring device comprising a U-shapedpivot support l4 formed of sheet metal bent to provide an'intermediateportion 15 having an arcuate tonguelike projection l5 'and to provide apair of triangularly-shaped arms I1, each having adjacent the lower endof the portion [5, an aperture receiving a pivot pin I8 and having atthe upper end an aperture receiving one end of the bail l9. Pivotallymounted on the pin la is a circular snubbing and clamping element 20,.This element comprisesa pair of discs 2| and 22 (Fig. 6) having theirrespective peripheries beveled inwardly to provide an annular snubbinggroove 23 for receiving the looped end of the cable {3. These discs maybe secured together in any Wellknown manner, not shown. As clearlyillustrated, the disc 2| has a depending pivot arm 24 which is pivotedon the pin 18 and supports the element 20 as a whole.

The device illustrated in the drawings operates as'follows: When it isdesired to engage a cable with the device, the element 20 will be movedabout the pin l8 until it depends downwardly with reference to Fig. 5and the looped end of the cable l3 will be passed between the arms I!from above until it extends a sufiicient distance below the arm topermit insertion of the element 20 within the loop and disposing theloop in the annular groove 23.

After the cable has thus been engaged with the element 20, it will bepulled back between the arms 11, thereby carrying with it the element20. Continued movement as described will lc'ause' theelement 20 to forcethe cable into clamping engagement with the portion l5 and tongue 16.cured to a support, the tension of the cable will hold it securelyanchored to the device.

From the foregoing disclosure, it will be apparent that acable-anchoring device has been provided in which a combined snubbingand clamp- 'ing action is secured by means of a single element 'movably.supported upon a clamping member, that'a'device has been provided inwhich tension upon a cable is utilized to cause clamping engagementtherewith, that a device has been provided in which the movable snubbingand clamping element may be moved to a position relative to its supportpermitting the looped end of a cable to be passed through the supportand engaged with the element for movement therewith to clampingengagement with the support, and that a single,

of a circular snubbing element pivotally and slidably mounted on one ofsaid sides for movement thereon to positions between said sides andwholly removed therefrom alternatively, said yoke member having aclamping portion connect- :ing said sides and cooperative with theperiphery of the snubbing element to clamp a .tensioned Obviously, whenthe bail I9 is secable thereto, the pivotal movement of said elementbeing'about an axis substantially parallel relative to said sides.

2. In a cable-anchoring device, a pivot support having spacedsubstantially parallel sides the corresponding ends of said sides beingintegrally connected to provide a clamping portion atone end and a bailportion at the other end,

in combination with a snubbing element having a circular snubbingsurface cooperative with said clamping portion for clamping a cablethereto and normally positioned between said sides, said snubbingelement including a portion pivotally supporting said element from oneof said sides for movement in an arcuate direction thereabout to aposition in which the snubbing surface is removed in its entirety frombetween said sides, whereby a looped cable portion may be passed betweensaid sides and said snubbing surface passed through said loop prior tothe return of the snubbing surface to a position between said sides.

3. In a cable-anchoring device, the combination with a substantiallyrectangular slide member having spaced parallel sides terminating at oneend in a bail portion and at the other end in a clamping portion, of acircular snubbing element having its axis transversely related to saidsides when operatively engaged with a cable, said element beingpivotally mounted for movement in an arcuate direction about one of saidsides and slidably mounted for movement longitudinally on said one ofsaid sides and provided with a shouldered portion engageable with theother of said sides to limit pivotal movement of said element in onedirection.

4. In acable-anchoring device, the combination with a U-shaped memberhaving a pair of arms and a clamping portion connecting said arms, of asnubbing element provided with an arcuate snub groove and positionedbetween said arms, said element being pivotally mounted on said memberat a point radially remote from the axis of said groove and from saidgroove and in a direction axially offset from said groove for movementtoward said clamping portion, and a 'bail secured to said member remotefrom said clamping portion.

5. In a cable-anchoring device, the combination with a slide memberhaving substantially spaced parallel sides closed at each end, asnubbing element pivotally and slidably mounted on one of said sides andprovided with a shouldered portion engageable with the other of saidsides to limit pivotal movement of said element in one direction.

6. A cable anchoring device comprising a member having substantiallyparallel sides integrally joined at corresponding ends to provide asnubbing portion, and a snubbing element having a cylindrical snubbingsurface and a pivot portion offset radially of the axis of and laterallyof said snubbing surface, said pivot portion being pivotally connectedwith one side only of said member, said snubbing surface being normallydisposed between said sides for cooperation with said snubbing portionand movable about said pivot to a position disposing said snubbingsurface with its entire cylindrical snubbing surface wholly removed frombetween said sides, whereby a looped end of a cable maybe passed betweensaid sides and said cylindrical snubbing surface disposed within saidloop.
